Pure essential olis have the highest quality?
By Marco Valussi
No. We can give a fairly straightforward definition of what we mean by pure essential oils: an essential oil is pure when it is identical to the material obtained by the production apparatus (steam distillation or squeezing machine for citrus peels), apart from simple mechanical filtering operations. That being said, a pure product may be of low quality, because there is no link between the two concepts. I can distill pure 100% lavender, but the quality of the oil will come from other factors:
- the origin of the plant
- when and how it has been harvested
- how it has been distilled
- for how long
- in water or in steam
In addition to the fact that the concept of quality is always dependent on the context of use, so it is variable and not fixed.
So, if the term "pure" is not accompanied by stronger guarantees, and if it is not associated with quality research, it is reduced to a mere marketing tool.
In addition, the link to safety is even more labile. "Pure" just means that it contains all the molecules it should contain, and if there are dangerous or toxic molecules in the chemical make-up, such as tujone or β-asarone, a pure oil will be toxic, while an oil fractionated to remoce the toxic elements will be safer, although less "pure.
Dilution is important: essential oils must always be diluted, as a generic precautionary measure, and dilution can make oil safer.
